If p side of the diode was connected to Vin and n side to Vout then answer would have been 4th option as Vout would be -ve as Vin is +ve to make the diode conduct and also as input is given to inverting terminal.

[@physica2153]

Yeah!! Right bro

[@theanimals4649]

[@deepanshu8711]

But i think the option with negative sign should also be correct??

[@physica2153]

Yes!! They should have mentioned the negative sign of input voltage

[@akaraesthetics9918]

sir log of -ne value is not allowed so may be they have assumed modules

[@physica2153]

Yes!! Maybe
